Description

Scanning tunneling microscopy (STM) is a scanning probe microscopy (SPM) imaging technique that takes advantage of the extreme distance sensitivity of the tunneling current between two conducting electrodes. By measuring the tunnel-current variations as a probe is scanned over a sample’s surface, STM is able to deliver the highest resolution SPM images.

The STM scanner is designed to deliver outstanding results on a variety of conducting materials. This low-current and ultra-low current STM scanner provides stable imaging at pico-ampere and sub-pico-ampere currents to resolve individual atoms and molecules. Over the past twenty years, Keysight STM scanners have delivered superior research results and have consistently outperformed other STM scanners in achieving the best atomic resolution within the shortest time.
